Jack Leiter is a position player for the Texas Rangers. In 2025 he hit 0 home runs and knocked in 0 RBIs, notching 0 hits across 1 plate appearances in 1 game. His batting average was .000, 100.0% lower than the league average of .245. He reached base at a .000 clip and slugged .000, for an OPS of .000, 100.0% lower than the league mark of .719. Adjusted for his ballpark and league, his -128 wRC+ puts his offence 228% below average. That comes to -0.0 dbWAR — -0.3 runs with the bat, +0.0 on the bases, -0.0 for the position he plays, against replacement level. It includes no fielding: defensive runs are proprietary and are not estimated here, so the figure credits playing a demanding position but not playing it well.

How these are computed

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
